Hi, There, everybody, 9 00:00:31,360 --> 00:00:35,080 Speaker 1: and welcome to tech Stuff. My name is Chris Polette. 10 00:00:35,240 --> 00:00:37,160 Speaker 1: I'm an editor here at how stuff works dot com, 11 00:00:37,200 --> 00:00:39,440 Speaker 1: and sitting next to me, as usual, is the very 12 00:00:39,479 --> 00:00:45,800 Speaker 1: helpful senior writer Jonathan Strickland. You know what I think 13 00:00:45,800 --> 00:00:48,240 Speaker 1: you need help? Do I? Yes, when I need help? 14 00:00:49,560 --> 00:00:54,040 Speaker 1: Do you? Because you're in the United States that it 15 00:00:54,040 --> 00:00:56,680 Speaker 1: occurred to me after we researched this that it is 16 00:00:56,720 --> 00:00:59,920 Speaker 1: once again a very United States centric podcast, So we 17 00:01:00,040 --> 00:01:03,840 Speaker 1: apologize to our friends overseas and to the north and South. 18 00:01:03,920 --> 00:01:07,319 Speaker 1: And okay, okay, well, let's let's just say, how does 19 00:01:07,720 --> 00:01:10,880 Speaker 1: a rescue number fill in the blank? Here? You know 20 00:01:11,040 --> 00:01:15,480 Speaker 1: where you are. Well, you're making some pretty big assumptions there, Pete, 21 00:01:15,480 --> 00:01:18,840 Speaker 1: because I haven't looked into any others other than one. Okay, well, 22 00:01:18,880 --> 00:01:21,000 Speaker 1: I think the technology is basically there, so let's talk 23 00:01:21,040 --> 00:01:24,480 Speaker 1: about the same. Alright, So let's first talk about how 24 00:01:24,600 --> 00:01:27,360 Speaker 1: nine one one is set up. We were gonna really 25 00:01:27,800 --> 00:01:30,800 Speaker 1: focus kind of on on how it works when you're 26 00:01:30,880 --> 00:01:35,720 Speaker 1: using a cellular phone or heaven help you avoid phone. Um. 27 00:01:35,800 --> 00:01:38,319 Speaker 1: But but before we get into that, it's best to 28 00:01:38,360 --> 00:01:40,120 Speaker 1: know kind of the basics of how it works in 29 00:01:40,160 --> 00:01:42,480 Speaker 1: the first place. Sure, I mean, it wasn't all that 30 00:01:42,520 --> 00:01:46,080 Speaker 1: long ago that there wasn't any kind of standardized number, 31 00:01:46,640 --> 00:01:48,680 Speaker 1: you know. You know, it's only been since the mid 32 00:01:48,760 --> 00:01:52,560 Speaker 1: nineteen sixties that for the sixties eight was when the 33 00:01:52,640 --> 00:01:55,320 Speaker 1: first one went live, right, Well, I mean they had to, 34 00:01:55,600 --> 00:01:58,960 Speaker 1: you know, work on getting it organized and it wasn't 35 00:01:58,960 --> 00:02:01,600 Speaker 1: even a national thing. It is very localized and it's 36 00:02:01,600 --> 00:02:03,920 Speaker 1: still listen, it's it's it is. It is very much 37 00:02:03,920 --> 00:02:07,600 Speaker 1: a regional system. So um, yeah, there's no national system. 38 00:02:07,640 --> 00:02:11,840 Speaker 1: It's all uh managed by by different counties and cities. 39 00:02:12,600 --> 00:02:17,079 Speaker 1: Yeah yeah, different uh, different governments and and different regions 40 00:02:17,120 --> 00:02:22,040 Speaker 1: are overseeing these things. So as you can imagine, coordination 41 00:02:22,160 --> 00:02:25,720 Speaker 1: is a is kind of a tricky, tricky business. One 42 00:02:25,800 --> 00:02:29,120 Speaker 1: and um, usually you know you're you're pretty much supporting 43 00:02:29,160 --> 00:02:32,280 Speaker 1: it through taxes and uh maybe a fee to your 44 00:02:32,400 --> 00:02:36,519 Speaker 1: phone carrier. Yeah, yeah, I mean it's uh. In addition 45 00:02:36,560 --> 00:02:38,560 Speaker 1: to building out the network, they have to pay people 46 00:02:38,600 --> 00:02:42,080 Speaker 1: to sit at the switchboard and listen to people with 47 00:02:42,160 --> 00:02:45,000 Speaker 1: emergency calls and those people who call to complain about 48 00:02:45,000 --> 00:02:47,560 Speaker 1: traffic and that there are no chicken nuggets at the McDonald's. 49 00:02:47,720 --> 00:02:49,959 Speaker 1: You totally stole it before I could say it. Yes, 50 00:02:50,200 --> 00:02:54,200 Speaker 1: I win, okay, so um, yes, uh, let's let's say 51 00:02:54,280 --> 00:02:57,679 Speaker 1: let's start with the landline um approach, because that that's 52 00:02:57,680 --> 00:02:59,600 Speaker 1: the easiest one to talk about when you're when you're 53 00:02:59,600 --> 00:03:02,200 Speaker 1: making a call, and it is the first one they 54 00:03:02,200 --> 00:03:04,919 Speaker 1: had to, uh to worry about building out. Right, so 55 00:03:04,960 --> 00:03:07,800 Speaker 1: when you actually dial, it goes to a different hub. 56 00:03:07,840 --> 00:03:10,919 Speaker 1: It doesn't actually go to the same hub that regular 57 00:03:10,960 --> 00:03:13,120 Speaker 1: phone call will go, right, because the phone company knows 58 00:03:13,240 --> 00:03:15,360 Speaker 1: when you make a phone call, it has to that's right, 59 00:03:15,440 --> 00:03:18,519 Speaker 1: that's right for them to bill you exactly exactly. So 60 00:03:18,560 --> 00:03:20,600 Speaker 1: when you make a nine one one call, the phone 61 00:03:20,600 --> 00:03:23,040 Speaker 1: company knows you're making an emergency call. It goes through 62 00:03:23,080 --> 00:03:26,280 Speaker 1: this hub and then it goes to the closest public 63 00:03:26,360 --> 00:03:31,119 Speaker 1: Safety Answering Point or P s a P SAP SAP, 64 00:03:31,320 --> 00:03:34,000 Speaker 1: so it goes to the closest one to whatever region 65 00:03:34,000 --> 00:03:37,119 Speaker 1: you're calling from. So that way the response is going 66 00:03:37,120 --> 00:03:40,840 Speaker 1: to be very localized and theoretically will be the fastest 67 00:03:40,880 --> 00:03:46,880 Speaker 1: response that you could expect under you know, any normal circumstances. Now, UM, 68 00:03:46,960 --> 00:03:50,240 Speaker 1: when you call the the phone company sends to that 69 00:03:51,080 --> 00:03:55,440 Speaker 1: SAP P s a P. That the your information, so 70 00:03:55,720 --> 00:03:58,280 Speaker 1: that person will know the operator will know like this 71 00:03:58,320 --> 00:04:00,840 Speaker 1: is where the phone calls originating. UM, in case you 72 00:04:00,880 --> 00:04:06,080 Speaker 1: aren't able to speak, If you are unable to actually talk, UH, 73 00:04:06,320 --> 00:04:08,280 Speaker 1: they can at least see where the calls coming from 74 00:04:08,280 --> 00:04:11,800 Speaker 1: and send help to that address. And this happens, you know, 75 00:04:11,960 --> 00:04:14,360 Speaker 1: more often than you would think. You may not be 76 00:04:14,480 --> 00:04:18,359 Speaker 1: able to speak because you smoke inhalation, you might be 77 00:04:18,440 --> 00:04:22,480 Speaker 1: choking on something. In some cases, people's pets have dialed 78 00:04:22,640 --> 00:04:27,960 Speaker 1: dialed one, and in some cases it was necessary. I 79 00:04:27,960 --> 00:04:30,000 Speaker 1: mean more than one case you had an animal dial 80 00:04:30,080 --> 00:04:32,280 Speaker 1: nine one one and it really didn't need to do that. 81 00:04:32,400 --> 00:04:37,200 Speaker 1: But but there are stories about rescue animals that did 82 00:04:37,240 --> 00:04:41,920 Speaker 1: dial nine one in order to contact UH emergency services 83 00:04:41,920 --> 00:04:45,280 Speaker 1: when their their owners. UM suffered some sort of trauma 84 00:04:45,960 --> 00:04:48,200 Speaker 1: and uh, you know, of course that doesn't happen all 85 00:04:48,200 --> 00:04:50,920 Speaker 1: that often. But the way the system works is the 86 00:04:50,960 --> 00:04:53,360 Speaker 1: operator sees, okay, this call is coming from this address, 87 00:04:53,400 --> 00:04:55,960 Speaker 1: I will send help there. I can't quite ascertain exactly 88 00:04:56,000 --> 00:04:58,480 Speaker 1: what's going on, and so they, you know, pretty much 89 00:04:58,520 --> 00:05:03,880 Speaker 1: decide at the spur of the moment which services to send. UM. Otherwise, 90 00:05:03,920 --> 00:05:07,040 Speaker 1: of course the dispatcher will talk to the you know, 91 00:05:07,160 --> 00:05:09,159 Speaker 1: the operator or dispatch will talk to you, and then 92 00:05:09,240 --> 00:05:12,280 Speaker 1: you would explain what the emergency situation was, and then 93 00:05:12,320 --> 00:05:17,840 Speaker 1: they would send the appropriate respond respondents. Right. So UM, 94 00:05:17,880 --> 00:05:22,560 Speaker 1: that's the that's just the basic uh response. There's actually 95 00:05:22,600 --> 00:05:26,240 Speaker 1: another thing called the enhanced nine one one response, which 96 00:05:26,279 --> 00:05:29,160 Speaker 1: is even a little more complex than that. Yeah, E 97 00:05:29,560 --> 00:05:33,039 Speaker 1: nine one one is UM actually fairly common now, I 98 00:05:33,040 --> 00:05:36,920 Speaker 1: would think, yeah, yeah, back in two thousand and six, 99 00:05:37,000 --> 00:05:40,200 Speaker 1: I think it was penetration in the market, So by 100 00:05:40,240 --> 00:05:43,160 Speaker 1: now I would expect that number to be much higher. 101 00:05:43,960 --> 00:05:48,279 Speaker 1: So UM, and it actually uses an even more sophisticated system. 102 00:05:48,320 --> 00:05:51,560 Speaker 1: The hub that you dial into UM actually makes some 103 00:05:51,680 --> 00:05:57,240 Speaker 1: additional determinations, goes in and get some info from a 104 00:05:57,279 --> 00:06:00,240 Speaker 1: couple of servers on the telephone system side to try 105 00:06:00,320 --> 00:06:04,320 Speaker 1: to get even more detailed information about where you are 106 00:06:04,360 --> 00:06:06,680 Speaker 1: and and who to route the call to to maybe 107 00:06:06,800 --> 00:06:09,920 Speaker 1: speed up the service just that much more. Right, Yeah, 108 00:06:10,000 --> 00:06:12,960 Speaker 1: you're talking about things like, you know, to everything from 109 00:06:13,000 --> 00:06:17,640 Speaker 1: determining how many emergency calls are already out to you know, 110 00:06:17,720 --> 00:06:21,240 Speaker 1: maybe maybe this person's address would make you think that 111 00:06:21,279 --> 00:06:23,800 Speaker 1: they are closest to this P s a P, but 112 00:06:23,839 --> 00:06:27,479 Speaker 1: in reality they'd be closer to another one. Um. It 113 00:06:27,560 --> 00:06:30,960 Speaker 1: also will bring up information such as what what sort 114 00:06:30,960 --> 00:06:35,880 Speaker 1: of obstacles a response team might encounter en route to 115 00:06:36,160 --> 00:06:39,479 Speaker 1: the address, like if there's a street that's closed or 116 00:06:40,360 --> 00:06:44,240 Speaker 1: anything along those lines. Um. So it really is of 117 00:06:44,279 --> 00:06:48,440 Speaker 1: course designed to help these emergency responders get to you 118 00:06:48,880 --> 00:06:52,880 Speaker 1: much more quickly and safely than they would otherwise. And 119 00:06:52,920 --> 00:06:56,760 Speaker 1: as it turns out, this enhanced nine one one functionality 120 00:06:56,800 --> 00:07:02,320 Speaker 1: is essential to getting wireless nine one functionality to to 121 00:07:02,440 --> 00:07:05,640 Speaker 1: actually function the right way, because otherwise it would be 122 00:07:05,720 --> 00:07:08,839 Speaker 1: very difficult for the the wireless provider to get the 123 00:07:08,880 --> 00:07:12,360 Speaker 1: information on where you are now. You know, a cell 124 00:07:12,400 --> 00:07:16,480 Speaker 1: phone can only be so accurate as to where they 125 00:07:16,520 --> 00:07:19,400 Speaker 1: can figure out where your location is because it's triangulating 126 00:07:19,720 --> 00:07:22,640 Speaker 1: based on the signals from different cell phone towers in 127 00:07:22,680 --> 00:07:25,840 Speaker 1: your area. Uh. So it's a little like GPS in 128 00:07:25,880 --> 00:07:28,800 Speaker 1: that way, because it is is determining your location based 129 00:07:28,880 --> 00:07:33,360 Speaker 1: on the transmitters on the ground and where the phone 130 00:07:33,400 --> 00:07:36,240 Speaker 1: is telling it that it is. You know, it seems 131 00:07:36,240 --> 00:07:38,280 Speaker 1: closer to this one, it seems rather away from that one. 132 00:07:38,320 --> 00:07:40,760 Speaker 1: We think he or she is in this area right here. 133 00:07:41,320 --> 00:07:46,560 Speaker 1: And UM, this is important because around of all phone 134 00:07:46,600 --> 00:07:51,480 Speaker 1: calls that go into originate from a wireless phone like 135 00:07:51,640 --> 00:07:56,360 Speaker 1: a cell phone. And UM, obviously when you have that 136 00:07:56,360 --> 00:07:58,240 Speaker 1: that number of calls coming in, you do need a 137 00:07:58,240 --> 00:08:01,960 Speaker 1: way that you can, you know, retained where this person is. Um. 138 00:08:02,000 --> 00:08:04,400 Speaker 1: There are a couple of different ways of doing this 139 00:08:04,520 --> 00:08:08,760 Speaker 1: besides the one you mentioned is probably the most common. Uh. 140 00:08:08,880 --> 00:08:13,320 Speaker 1: That one is the uh it's a network based location 141 00:08:13,400 --> 00:08:15,320 Speaker 1: finding is kind of the way we think of it. 142 00:08:15,320 --> 00:08:18,920 Speaker 1: It's in the sense that it's all based upon how 143 00:08:18,960 --> 00:08:21,480 Speaker 1: far away you are from at least usually I think 144 00:08:21,520 --> 00:08:24,040 Speaker 1: three towers that's what they need in order to to 145 00:08:24,160 --> 00:08:27,360 Speaker 1: determine where in general you are. I think that's the 146 00:08:27,440 --> 00:08:32,360 Speaker 1: number that I saw most frequently. And yeah, it's it's 147 00:08:32,400 --> 00:08:36,360 Speaker 1: accurate to between one dred three, which is you know, 148 00:08:36,440 --> 00:08:40,200 Speaker 1: not that bad considering, but there's if you're you know, 149 00:08:40,240 --> 00:08:42,720 Speaker 1: in your car and it's on fire with flame shooting 150 00:08:42,760 --> 00:08:44,640 Speaker 1: out through the hood, I think they'd probably be able 151 00:08:44,679 --> 00:08:47,120 Speaker 1: to find you once they got once they got within 152 00:08:47,120 --> 00:08:49,240 Speaker 1: three they probably be able to figure out what they know. 153 00:08:49,720 --> 00:08:52,199 Speaker 1: But the other way you can do this is actually 154 00:08:52,280 --> 00:08:55,640 Speaker 1: using a handheld device like your Your phone itself has 155 00:08:55,840 --> 00:08:59,200 Speaker 1: within it a location device that would help in that. 156 00:09:00,120 --> 00:09:02,400 Speaker 1: If you have a phone that has a GPS receiver, 157 00:09:03,080 --> 00:09:06,760 Speaker 1: it could it could send the information it's receiving from 158 00:09:06,800 --> 00:09:12,000 Speaker 1: the satellite on through the signal and therefore give extremely 159 00:09:12,040 --> 00:09:16,400 Speaker 1: accurate location information to whomever's on the phone. Right, So 160 00:09:16,440 --> 00:09:18,760 Speaker 1: it's getting the the information from the GPS and sending 161 00:09:18,760 --> 00:09:21,599 Speaker 1: it over the cell phone network, right, That's exactly what 162 00:09:21,679 --> 00:09:24,600 Speaker 1: it's doing. However, you have to keep in mind if 163 00:09:24,600 --> 00:09:27,840 Speaker 1: you're inside, that's not going to help you out too much. 164 00:09:28,040 --> 00:09:30,080 Speaker 1: You really need to have an open view to the 165 00:09:30,120 --> 00:09:33,640 Speaker 1: sky in order to to really get those signals from 166 00:09:33,760 --> 00:09:37,400 Speaker 1: the satellites. Uh, if you are in any kind of 167 00:09:37,400 --> 00:09:41,000 Speaker 1: like heavily wooded area or maybe downtown in a really 168 00:09:41,120 --> 00:09:44,600 Speaker 1: crowded city, um, it may not respond as well. So 169 00:09:44,760 --> 00:09:47,640 Speaker 1: that's not always necessarily, Like, just because you have a 170 00:09:47,679 --> 00:09:50,760 Speaker 1: GPS receiver in your phone doesn't necessarily mean it's going 171 00:09:50,800 --> 00:09:53,320 Speaker 1: to give it the most accurate information all the time. 172 00:09:53,440 --> 00:09:55,280 Speaker 1: It all depends on the situation you're in and the 173 00:09:55,360 --> 00:09:58,760 Speaker 1: environment around you. That's true, because I'm guessing that if 174 00:09:58,800 --> 00:10:02,120 Speaker 1: you were saying in a the story building and you 175 00:10:02,160 --> 00:10:05,720 Speaker 1: have a GPS device and it's saying, well, you know 176 00:10:05,800 --> 00:10:09,520 Speaker 1: he's here at this location, then the rescuers have to 177 00:10:09,559 --> 00:10:12,679 Speaker 1: go look on every floor because it doesn't say, well, 178 00:10:12,679 --> 00:10:15,079 Speaker 1: you know he's on the fifth floor and sweet five forty, 179 00:10:16,240 --> 00:10:18,559 Speaker 1: so well yeah, yeah, so even if it could get 180 00:10:18,559 --> 00:10:20,319 Speaker 1: the signal in the first place, so there, so there 181 00:10:20,400 --> 00:10:22,719 Speaker 1: is a limit, Yeah, there are there are limits. And 182 00:10:23,679 --> 00:10:25,480 Speaker 1: the whole reason for this in the first place is 183 00:10:25,520 --> 00:10:29,440 Speaker 1: because the the FCC was very much concerned with making 184 00:10:29,480 --> 00:10:31,920 Speaker 1: sure that when you dial nine one one on a 185 00:10:32,000 --> 00:10:34,360 Speaker 1: cell phone that you are able to get the help 186 00:10:34,440 --> 00:10:39,080 Speaker 1: that you require, and uh, they demanded demanded things to 187 00:10:39,080 --> 00:10:41,880 Speaker 1: be rolled out the sort of the enhanced nine one 188 00:10:41,880 --> 00:10:44,280 Speaker 1: one for cell phones to be rolled out into two phases. 189 00:10:44,880 --> 00:10:49,240 Speaker 1: The first phase was just using location determining your location 190 00:10:49,280 --> 00:10:52,360 Speaker 1: will be determined based upon whichever cell tower you are 191 00:10:52,360 --> 00:10:56,079 Speaker 1: connecting to with your phone, and unfortunately that doesn't really 192 00:10:56,440 --> 00:10:59,240 Speaker 1: give you a whole lot of accuracy. We're talking like 193 00:11:00,080 --> 00:11:04,880 Speaker 1: six to thirty miles, and six to thirty miles is 194 00:11:04,920 --> 00:11:07,600 Speaker 1: not great. Now, hopefully, if you are actually able to 195 00:11:07,600 --> 00:11:11,040 Speaker 1: communicate with the operator, that won't be as big a 196 00:11:11,080 --> 00:11:13,400 Speaker 1: deal because you'll be able to tell that person where 197 00:11:13,440 --> 00:11:16,520 Speaker 1: you are right right under Phase two. It's it's much 198 00:11:16,559 --> 00:11:22,720 Speaker 1: more accurate within fifty according to the government information. And uh, 199 00:11:22,800 --> 00:11:24,719 Speaker 1: I was actually looking into this now. Here's the other 200 00:11:24,760 --> 00:11:26,559 Speaker 1: issue is that you might wonder, like, okay, well, how 201 00:11:26,600 --> 00:11:31,000 Speaker 1: far into phase two are we? That is practically impossible 202 00:11:31,120 --> 00:11:34,880 Speaker 1: to answer without contacting each and every P s A 203 00:11:35,000 --> 00:11:39,360 Speaker 1: P in the nation because it's on a per carrier basis. 204 00:11:39,360 --> 00:11:42,120 Speaker 1: It's on a per P S a P basis. They 205 00:11:42,200 --> 00:11:44,520 Speaker 1: have to work together in order to get this Phase 206 00:11:44,600 --> 00:11:49,840 Speaker 1: two rolled out. So um yeah, it's I couldn't even 207 00:11:49,840 --> 00:11:55,160 Speaker 1: tell you, like, how how many different locations have Phase 208 00:11:55,200 --> 00:11:59,560 Speaker 1: two rolled out versus Phase one? Um, it's uh and 209 00:11:59,600 --> 00:12:01,800 Speaker 1: that's kind of scary when you think about it. I mean, 210 00:12:01,920 --> 00:12:03,760 Speaker 1: you know, you really don't know when you call nine 211 00:12:03,800 --> 00:12:07,480 Speaker 1: one one if how accurate their their information is going 212 00:12:07,520 --> 00:12:10,800 Speaker 1: to be um. Of course if you can talk, then 213 00:12:11,440 --> 00:12:13,760 Speaker 1: that might be able to solve some issues right there. 214 00:12:13,800 --> 00:12:17,200 Speaker 1: But yeah, you know, uh, just to point this out, UM, 215 00:12:17,240 --> 00:12:20,480 Speaker 1: from what I was reading during my research fees on 216 00:12:20,520 --> 00:12:23,640 Speaker 1: this podcast, Uh, the experts say the very first thing 217 00:12:23,679 --> 00:12:25,880 Speaker 1: you should do when you call nine one one is 218 00:12:25,920 --> 00:12:31,320 Speaker 1: to tell them where you are. Um. Especially yeah, exactly 219 00:12:31,360 --> 00:12:33,760 Speaker 1: because they said that that that is probably the most 220 00:12:34,080 --> 00:12:36,800 Speaker 1: important thing, especially if you're in a situation where you're 221 00:12:36,840 --> 00:12:40,520 Speaker 1: not able to communicate well, because um, you know, then 222 00:12:40,559 --> 00:12:43,400 Speaker 1: they can go ahead and figure out how to get 223 00:12:43,440 --> 00:12:47,040 Speaker 1: to you and from there, you know, assist you. But yeah, 224 00:12:47,120 --> 00:12:49,440 Speaker 1: that's you know, don't forget to just go ahead and 225 00:12:49,440 --> 00:12:52,839 Speaker 1: tell them where you are, um, because that is is 226 00:12:53,480 --> 00:12:56,439 Speaker 1: essential when you're dealing with wireless and v O I P. 227 00:12:57,640 --> 00:13:01,000 Speaker 1: I didn't think to at this in my notes, But 228 00:13:01,040 --> 00:13:03,240 Speaker 1: we should also addressed the fact that if you carry 229 00:13:03,480 --> 00:13:07,559 Speaker 1: a satellite phone, that can give information very quickly to 230 00:13:07,760 --> 00:13:10,400 Speaker 1: an emergency response team exactly where you are. Because again 231 00:13:10,440 --> 00:13:13,720 Speaker 1: that's working on the same sort of of uh kind 232 00:13:13,760 --> 00:13:16,880 Speaker 1: of way as a GPS receiver. You're receiving yourself signals 233 00:13:16,880 --> 00:13:20,600 Speaker 1: through satellite UM, and there are many satellite emergency phones 234 00:13:20,679 --> 00:13:23,840 Speaker 1: that are on the market for people who like, you know, 235 00:13:24,000 --> 00:13:27,040 Speaker 1: like to hike in the Yukon. Sure's things like that. 236 00:13:27,080 --> 00:13:29,640 Speaker 1: You know, people who really do go into these you know, 237 00:13:29,720 --> 00:13:34,440 Speaker 1: high risk environments because they're they're adventurers at heart, and uh, 238 00:13:34,720 --> 00:13:38,560 Speaker 1: these sort of phones help help get that information out. 239 00:13:38,559 --> 00:13:40,800 Speaker 1: And usually it's a simple button you press and it 240 00:13:40,840 --> 00:13:45,360 Speaker 1: sends an emergency signal and it includes your coordinates like 241 00:13:45,480 --> 00:13:48,199 Speaker 1: on Star in cars. Yeah, essentially, yeah, it's on Star 242 00:13:48,280 --> 00:13:52,360 Speaker 1: for hikers. Yeah. And very expensive. Yes, yes, they are 243 00:13:52,440 --> 00:13:55,679 Speaker 1: not cheap. Yeah, we're not talking like your voice plan. 244 00:13:55,800 --> 00:13:58,720 Speaker 1: I think they're significantly right. Both the phones and the 245 00:13:58,840 --> 00:14:01,400 Speaker 1: plans cost quite an out of money. But if it's 246 00:14:01,400 --> 00:14:03,840 Speaker 1: a matter of life and death because you're an adventurer 247 00:14:03,840 --> 00:14:06,800 Speaker 1: and like like to go out and you know, party 248 00:14:06,840 --> 00:14:10,280 Speaker 1: with grizzly bears who might eat you and who doesn't write, 249 00:14:11,160 --> 00:14:13,240 Speaker 1: you know, I might be worth the investment. So let's 250 00:14:13,240 --> 00:14:18,440 Speaker 1: move on to voipe over Internet protocol. That's true. Now, 251 00:14:18,640 --> 00:14:21,480 Speaker 1: voice over Internet protocol we've talked about before in this podcast. 252 00:14:21,640 --> 00:14:24,640 Speaker 1: This is uh, yeah, this is uh, this is It 253 00:14:24,760 --> 00:14:27,600 Speaker 1: sends your phone call like it would send it sends 254 00:14:27,600 --> 00:14:31,440 Speaker 1: it over the internet esppecially over the cellular network, and uh, 255 00:14:31,560 --> 00:14:34,360 Speaker 1: like every other kind of information that's sent over the 256 00:14:34,360 --> 00:14:37,880 Speaker 1: internet's broken up into packets, gets little pieces, teeny tiny 257 00:14:37,920 --> 00:14:40,520 Speaker 1: pieces like you know, like a Mike TV and Willy 258 00:14:40,560 --> 00:14:42,640 Speaker 1: Wonka flies through the air, and it gets to the 259 00:14:42,640 --> 00:14:44,920 Speaker 1: other side and gets re it gets put back together, 260 00:14:44,960 --> 00:14:47,560 Speaker 1: and then it becomes the phone call on the other end. Uh. 261 00:14:47,600 --> 00:14:50,960 Speaker 1: Here's the problem with voipe. Um, there's no physical location 262 00:14:51,240 --> 00:14:55,360 Speaker 1: associated with voipe at all at all. You your voice 263 00:14:55,440 --> 00:14:59,680 Speaker 1: is associated mainly with your computer or device upon which 264 00:14:59,720 --> 00:15:02,840 Speaker 1: you have voipe installed. That's true, I mean there is 265 00:15:03,640 --> 00:15:06,840 Speaker 1: you know, you can ping something a location and get 266 00:15:06,880 --> 00:15:08,760 Speaker 1: as sort of an idea of where it's going to 267 00:15:08,880 --> 00:15:12,800 Speaker 1: because you know, and internet. Anything you send through the 268 00:15:12,880 --> 00:15:16,600 Speaker 1: Internet reaches lots of computers, tons and tons and tons 269 00:15:16,600 --> 00:15:20,000 Speaker 1: of computers because it's it's bouncing piece by piece over 270 00:15:20,480 --> 00:15:23,480 Speaker 1: you know, network by network, different stuff in between here 271 00:15:23,480 --> 00:15:27,560 Speaker 1: and there. The thing is, you know, there's very it's 272 00:15:27,680 --> 00:15:31,160 Speaker 1: this information that's coming around with it is very sketchy. 273 00:15:31,960 --> 00:15:37,800 Speaker 1: So it's you know, it's general idea of where someone is. 274 00:15:38,280 --> 00:15:40,640 Speaker 1: But the other thing is that, um, you know, it's 275 00:15:40,800 --> 00:15:44,480 Speaker 1: it's you can set a location when you set up 276 00:15:44,760 --> 00:15:48,560 Speaker 1: a voipe account. In fact, you're supposed to UM, which 277 00:15:48,720 --> 00:15:51,520 Speaker 1: would be you know, like the idea here is that 278 00:15:51,520 --> 00:15:54,480 Speaker 1: you're telling the company this is where I usually I 279 00:15:55,000 --> 00:15:57,600 Speaker 1: am usually at when I make my voice calls, like 280 00:15:57,680 --> 00:16:00,200 Speaker 1: if I I'm usually at home when I do this 281 00:16:00,320 --> 00:16:02,720 Speaker 1: VOPE system. So that way, if I were to ever 282 00:16:02,800 --> 00:16:05,760 Speaker 1: call nine one one over the VOPE system, chances are 283 00:16:05,960 --> 00:16:09,800 Speaker 1: this is the location that I'm calling from. UM. And 284 00:16:09,840 --> 00:16:12,320 Speaker 1: then theoretically you should have an easy way to update 285 00:16:12,360 --> 00:16:15,000 Speaker 1: that information so that if you were to travel, you 286 00:16:15,000 --> 00:16:19,280 Speaker 1: could say I happen to be in Prague. Not of course, 287 00:16:19,320 --> 00:16:21,040 Speaker 1: if you're in Prague, I don't know why you'd be 288 00:16:21,080 --> 00:16:24,880 Speaker 1: dialing one, but the point being that you should be 289 00:16:24,920 --> 00:16:28,600 Speaker 1: able to update your location so that UM, you're not 290 00:16:28,680 --> 00:16:32,560 Speaker 1: sending the operators on a married chase or really it's 291 00:16:32,640 --> 00:16:36,400 Speaker 1: just to let the phone company know which P s 292 00:16:36,440 --> 00:16:39,080 Speaker 1: a P you're calling needs to be rounded to. Yeah, 293 00:16:39,360 --> 00:16:40,920 Speaker 1: it's not gonna do much good if you call nine 294 00:16:41,000 --> 00:16:44,200 Speaker 1: one one and the person answering the phone is eight 295 00:16:44,240 --> 00:16:49,000 Speaker 1: counties away and uh, you know, it's just as all 296 00:16:49,000 --> 00:16:51,840 Speaker 1: that's gonna do is waste valuable seconds. And of course 297 00:16:51,920 --> 00:16:54,720 Speaker 1: we know like in an emergency, every second counts. Yeah, 298 00:16:54,760 --> 00:16:57,960 Speaker 1: if you're if you're a v O I P telephone customer, 299 00:16:58,080 --> 00:17:01,360 Speaker 1: for example, if you Advantage or many of the others. 300 00:17:01,560 --> 00:17:04,600 Speaker 1: A lot of the regular I s P s and 301 00:17:04,920 --> 00:17:07,000 Speaker 1: phone companies offer some kind of v O I P 302 00:17:07,160 --> 00:17:10,879 Speaker 1: service Now UM. They'll tell you whether or not you 303 00:17:10,880 --> 00:17:14,600 Speaker 1: can use UM, and they sort of have some of 304 00:17:14,600 --> 00:17:16,960 Speaker 1: the details ironed out. However, if you were to be 305 00:17:17,119 --> 00:17:22,480 Speaker 1: using some of the UM programs like Skype or Gizmo Project, 306 00:17:23,600 --> 00:17:25,840 Speaker 1: I don't know that it would be as reliable as 307 00:17:25,920 --> 00:17:28,240 Speaker 1: you know, something like Vantage, which is you know, set 308 00:17:28,320 --> 00:17:30,920 Speaker 1: up to be. It's like, well, we know where he lives, 309 00:17:31,040 --> 00:17:34,480 Speaker 1: he's calling from this address. It's fine. Now, the FCC 310 00:17:34,600 --> 00:17:41,200 Speaker 1: says that any VOIPE provider has to provide support and 311 00:17:41,359 --> 00:17:44,600 Speaker 1: it has to work. Uh. They don't go so far 312 00:17:44,640 --> 00:17:47,360 Speaker 1: as to explain how that's supposed to happen, but they 313 00:17:47,400 --> 00:17:49,600 Speaker 1: say this is how it has to be, so it's 314 00:17:49,680 --> 00:17:51,800 Speaker 1: left up to the providers to find a way to 315 00:17:51,840 --> 00:17:54,360 Speaker 1: make it work. Yeah, that's the thing. I mean, if 316 00:17:54,359 --> 00:17:57,200 Speaker 1: you're if they know that you have a voice power 317 00:17:57,320 --> 00:18:00,000 Speaker 1: line system at your house and you're calling from your house, 318 00:18:00,200 --> 00:18:02,119 Speaker 1: well they know where that is. They can it works. 319 00:18:02,160 --> 00:18:05,119 Speaker 1: It would work very similarly to a regular telephone call. 320 00:18:05,160 --> 00:18:07,680 Speaker 1: I would assume in that UM they would say, well, 321 00:18:08,320 --> 00:18:10,760 Speaker 1: h Chris is calling. We know Chris lives at this address, 322 00:18:11,320 --> 00:18:14,439 Speaker 1: send him here and that would be it. But you know, 323 00:18:15,000 --> 00:18:17,560 Speaker 1: it's not because of the voide. It's because they know 324 00:18:17,680 --> 00:18:21,040 Speaker 1: they already know where you live, right And according to 325 00:18:21,080 --> 00:18:25,440 Speaker 1: the f c C, interconnected voite providers must obtain affirmative 326 00:18:25,480 --> 00:18:28,760 Speaker 1: acknowledgement from all existing customers that they are aware of 327 00:18:28,800 --> 00:18:31,280 Speaker 1: and understand the limitations of their nine one one service, 328 00:18:31,440 --> 00:18:33,560 Speaker 1: and they do send that information to you if you're 329 00:18:33,560 --> 00:18:35,760 Speaker 1: a customer, because I am a v O I P customer, 330 00:18:35,840 --> 00:18:39,480 Speaker 1: so you actually received that excellent, So good on them. 331 00:18:39,800 --> 00:18:43,679 Speaker 1: They're following the law. UM. But yeah, it is important 332 00:18:43,720 --> 00:18:45,719 Speaker 1: to remember that if you're a void customer that that 333 00:18:45,800 --> 00:18:49,880 Speaker 1: could become uh an issue. However, we should also point 334 00:18:49,880 --> 00:18:53,640 Speaker 1: out that, UM, you can also make nine one one 335 00:18:53,680 --> 00:18:58,119 Speaker 1: calls from any cellular phone or really any landline. I 336 00:18:58,119 --> 00:19:00,200 Speaker 1: think I think you can make an emergency call all 337 00:19:00,280 --> 00:19:02,880 Speaker 1: no matter what, you don't even even if you don't 338 00:19:02,880 --> 00:19:04,879 Speaker 1: have a plan anymore on a cell phone. If you 339 00:19:04,920 --> 00:19:06,640 Speaker 1: pick up a cell phone in don nine one one, 340 00:19:07,119 --> 00:19:09,720 Speaker 1: it has to work, right, that's true. I mean that's 341 00:19:09,920 --> 00:19:12,280 Speaker 1: if you have an old cell phone. Um. I've actually 342 00:19:12,280 --> 00:19:17,040 Speaker 1: heard this mention before by a consumer. Um consumer rights 343 00:19:17,040 --> 00:19:20,000 Speaker 1: advocates said, if you have an old cell phone, you know, 344 00:19:20,000 --> 00:19:21,880 Speaker 1: traded in for a new one, go ahead and keep 345 00:19:21,880 --> 00:19:23,919 Speaker 1: it charged up, the old one and throw in your 346 00:19:23,960 --> 00:19:26,280 Speaker 1: glove compartment, because what if you leave your cell phone 347 00:19:26,280 --> 00:19:28,880 Speaker 1: at home, you get an accident, you still are supposed 348 00:19:28,880 --> 00:19:30,320 Speaker 1: to be able to call nine one one, and they're 349 00:19:30,320 --> 00:19:33,760 Speaker 1: still supposed to connect those emergency calls. So it's a 350 00:19:33,760 --> 00:19:35,960 Speaker 1: good use for an old, beat up phone. Yeah. I know, 351 00:19:36,040 --> 00:19:39,119 Speaker 1: there's some charity organizations that accept donations of old phones 352 00:19:39,160 --> 00:19:42,920 Speaker 1: specifically to use them as emergency phones for underserf populations. 353 00:19:43,880 --> 00:19:46,080 Speaker 1: So um, so yeah, that's that's a good thing to 354 00:19:46,200 --> 00:19:48,040 Speaker 1: keep in mind is even if you do use voide, 355 00:19:48,040 --> 00:19:51,680 Speaker 1: it may it may behoove you to keep a regular 356 00:19:51,720 --> 00:19:55,120 Speaker 1: old phone plugged in or a a cell phone laying 357 00:19:55,200 --> 00:19:56,960 Speaker 1: around so that you can rely on that in the 358 00:19:57,000 --> 00:19:59,760 Speaker 1: case of an emergency, just in case the voide doesn't 359 00:20:00,000 --> 00:20:03,040 Speaker 1: work exactly the way you would hope it would work, 360 00:20:03,280 --> 00:20:04,879 Speaker 1: and in which case you would want to tell them 361 00:20:04,880 --> 00:20:09,720 Speaker 1: where you are first. Yes, always remember that I'm done. 362 00:20:09,920 --> 00:20:13,439 Speaker 1: I am too excellent, because you know what that means. Yeah, 363 00:20:13,520 --> 00:20:21,479 Speaker 1: it's time for listener mail. Yay. I'm trying a new 364 00:20:21,480 --> 00:20:25,600 Speaker 1: approach this time. Yea, yeah, excellent, all right. This listener 365 00:20:25,600 --> 00:20:29,720 Speaker 1: mail comes from Andrew. Hi Andrew, He says hello, Hey, look, 366 00:20:29,720 --> 00:20:32,800 Speaker 1: he said hi back. My name is Andrew from Illinois. 367 00:20:33,000 --> 00:20:36,640 Speaker 1: So he's the Andrew from Illinois. Hi, Andrew and Illinois. 368 00:20:36,960 --> 00:20:39,800 Speaker 1: He's in seventh grade and I'm subscribed to what is 369 00:20:39,840 --> 00:20:43,960 Speaker 1: it now? Seven? Yeah? All seven How Stuff Works podcasts. 370 00:20:44,520 --> 00:20:48,000 Speaker 1: You are awesome, Andrew. I just thought i'd dropped you 371 00:20:48,040 --> 00:20:50,480 Speaker 1: a line. Aligned to you guys at tech stuff and 372 00:20:50,560 --> 00:20:53,880 Speaker 1: say the specifics about the five major web browsers Internet Explorer, 373 00:20:53,960 --> 00:20:58,680 Speaker 1: I have eight Mozilla, Firefox, Apple, Safari, Google, Chrome, and Opera. 374 00:20:58,760 --> 00:21:03,120 Speaker 1: I have all five on my laptop, and although Internet 375 00:21:03,119 --> 00:21:06,240 Speaker 1: Explorers the easiest to use, best for favorites and bookmarks 376 00:21:06,240 --> 00:21:08,680 Speaker 1: and a few other things, there's in no way the best. 377 00:21:08,960 --> 00:21:11,520 Speaker 1: Firefox is by far the best and safest of them all. 378 00:21:11,640 --> 00:21:14,080 Speaker 1: Safari is the fastest, Chrome is stripped down, making it 379 00:21:14,119 --> 00:21:16,800 Speaker 1: an easier interface to use, and Opera makes the best 380 00:21:16,840 --> 00:21:20,199 Speaker 1: backup browser and is great on older computers. I know 381 00:21:20,280 --> 00:21:22,040 Speaker 1: that you probably know all this already, but I just 382 00:21:22,080 --> 00:21:24,160 Speaker 1: wanted to say what I believe about them. I never 383 00:21:24,200 --> 00:21:26,600 Speaker 1: owned and hardly ever used a Mac before, by the way, 384 00:21:26,920 --> 00:21:29,840 Speaker 1: I just wanted to say that I am slash was 385 00:21:29,920 --> 00:21:36,240 Speaker 1: bared and it is PM by five pm and seventh grade. 386 00:21:36,280 --> 00:21:40,560 Speaker 1: Yeah that's okay, Yeah, I'm I'd say bedtime at ten. Yeah, 387 00:21:40,840 --> 00:21:45,080 Speaker 1: we'll ask my bedtime now too. Good Lord, well, Andrew, 388 00:21:45,119 --> 00:21:48,360 Speaker 1: thank you very much for writing it. Um five browsers 389 00:21:48,400 --> 00:21:52,000 Speaker 1: on one laptop. Oh, we'll see. That's that's because that's 390 00:21:52,119 --> 00:21:54,080 Speaker 1: you see, he's not using a Mac. Because if he 391 00:21:54,160 --> 00:21:58,639 Speaker 1: was using a Mac, you have those plus OmniWeb and 392 00:21:58,760 --> 00:22:02,960 Speaker 1: Camino at least if not, Shira, I'm almost sad that 393 00:22:03,000 --> 00:22:07,000 Speaker 1: I picked this mail to read. You know, you're right though, 394 00:22:07,040 --> 00:22:11,240 Speaker 1: because each browser they're all they're all good. Uh, and 395 00:22:11,320 --> 00:22:13,680 Speaker 1: it's it seems like from using all of them, there's 396 00:22:13,720 --> 00:22:16,560 Speaker 1: always one thing about each one of them that goes. Man. 397 00:22:16,600 --> 00:22:19,560 Speaker 1: I wish everybody else would do this, but they don't. Yeah. Yeah, 398 00:22:19,560 --> 00:22:20,960 Speaker 1: I can think right off the help of my head. 399 00:22:21,040 --> 00:22:24,480 Speaker 1: For instance, UM, i'd say the Internet Explorer probably has 400 00:22:24,520 --> 00:22:31,000 Speaker 1: the most widespread support any website to work in Internet Explorer. Um, 401 00:22:31,000 --> 00:22:34,080 Speaker 1: it's also out of the major ones, it's the slowest. 402 00:22:34,680 --> 00:22:38,600 Speaker 1: Although Internet Explorer eight is faster than seven. I think, 403 00:22:38,800 --> 00:22:41,240 Speaker 1: what was it, Safari was like thirty six times faster 404 00:22:41,359 --> 00:22:44,480 Speaker 1: than Internet Explore seven. Yeah, it's only like eight times 405 00:22:44,520 --> 00:22:50,359 Speaker 1: faster than Internet Explorer eight, so it's it's improved. But yeah, um, 406 00:22:50,480 --> 00:22:53,600 Speaker 1: actually I think and and Andrew sent this for a 407 00:22:53,600 --> 00:22:55,480 Speaker 1: while ago. I think I should point out that Google 408 00:22:55,520 --> 00:22:57,639 Speaker 1: Chrome doesn't have a new beta out that's even faster 409 00:22:58,280 --> 00:23:04,199 Speaker 1: and bite me, Safari. Disagree with you, Andrew. But they 410 00:23:04,240 --> 00:23:08,520 Speaker 1: had a contest not too long ago which they let crackers, 411 00:23:08,560 --> 00:23:11,240 Speaker 1: won't their white hat hackers take a shot at the 412 00:23:11,280 --> 00:23:16,199 Speaker 1: different Uh stop laughing at me the joke alright, go 413 00:23:16,240 --> 00:23:19,440 Speaker 1: ahead anyway, they let some some hackers take a shot 414 00:23:19,480 --> 00:23:21,960 Speaker 1: at the security on the different browsers, and the one 415 00:23:22,080 --> 00:23:25,560 Speaker 1: that withstood the attack the longest was not Firefox. It 416 00:23:25,760 --> 00:23:29,080 Speaker 1: was Chrome. Yeah. Chrome, actually did did they ever break it? 417 00:23:29,359 --> 00:23:31,600 Speaker 1: I didn't see a final I think they finally just 418 00:23:31,680 --> 00:23:33,359 Speaker 1: gave up at the end of the first day. That 419 00:23:33,440 --> 00:23:38,560 Speaker 1: was the only one that they hadn't actually managed to crack. Um, however, 420 00:23:38,600 --> 00:23:41,440 Speaker 1: you don't have all the extensions and flexibility of fires true? 421 00:23:41,640 --> 00:23:44,480 Speaker 1: Is that true? I I rely on Firefox primarily, and 422 00:23:44,480 --> 00:23:46,320 Speaker 1: then I use Chrome is my backup browser, and then 423 00:23:46,320 --> 00:23:49,280 Speaker 1: I use Internet Explorer for whenever I have to access anything. 424 00:23:49,520 --> 00:23:52,119 Speaker 1: Uh internally, I still have a soft spot in my 425 00:23:52,119 --> 00:23:55,560 Speaker 1: heart for opera, do you yeah? And Safari is pretty 426 00:23:55,960 --> 00:23:57,800 Speaker 1: you know, there's some good things about all of them. 427 00:23:58,040 --> 00:23:59,959 Speaker 1: I'm more of a musical fan than an opera fan, 428 00:24:00,000 --> 00:24:03,600 Speaker 1: and I'm just gonna stop with that. Okay, So I 429 00:24:03,640 --> 00:24:06,720 Speaker 1: guess that wratches things up.
